AIGOCEROS EQUINA. 
pastern-joint posteiiorly is of the same hue. Eyes deep orange-coloured 
brown. Hoofs liver-brown. Horns between yellowish and umber-brown. 
Form, &c.— Figure robust and elegantly proportioned. Head at and be- 
hind the eyes broad and deep, before the eyes comparatively narrow and 
delicate, — the transition from the one state to the other sudden. Neck very 
thick and powerful. Muzzle small and somewhat semilunar in shape, ante- 
riorly prolonged to the edge of the upper lip. Horns directly above the eyes 
and strongly recurved, the first two-thirds of each scabrous from elevated rings, 
the last third smooth and tapered. The number of rings varies according to 
the age of the animal, being generally in a well grown specimen from twenty 
to twenty-four, they are commonly most developed near where they cease to 
exist, and are generally very faint on the external aspect, probably from their 
being worn down by friction ; the animal being much addicted to the practice 
of rubbing its horns against trees, rocks, &c. The transverse section of 
a horn has a somewhat oval shape, the posterior portion being the 
broadest. The ears are situated about four and a half inches behind the 
horns, and are long, rather narrow and slightly falcated towards their tips ; 
the tips slightly obtuse and somewhat truncated ; internally they are lined 
with long soft hair, externally with a short and rigid sort. The crest of the 
neck is surmounted with a compressed thin mane which commences a few 
inches behind the ears, and terminates on the hollow of the back a short dis- 
tance behind the withers; it is highestwhere the neck joins the body, and lowest 
towards its origin and termination. For some inches behind the former the 
hair forming the mane, lies forwards, that of the other parts is nearly perpen- 
dicular. Withers a little elevated and slightly arched, not however to an 
extent to form a sensible hunch. Tail terminated by a small brush of long 
hair, the origin of which is sudden and well defined, above the brush the 
hairy covering is short, and on the under aspect of the tail very scanty. 
Hoofs rather small and each foot is furnished with an unguinal sinus ; in- 
guinal pores two ; inguinal mammae four. Hair covering the upper parts 
of the neck, the body and the extremities short, rigid and recumbent; that on 
the lower part of the neck long and rather shaggy.
